C. G. JOHNSON WINDOW CONSTRUCTION Filed July 25, 1928 Patented Mar. 24, 1931 UNITE SATES CLARENCE G. JOHNSON, OF lEARTFORD CITY, INDIANA wnvnow cons'rnnc'rron Application filed July 23, 1928. Serial No. 294,886.

The present invention pertains to a novel window construction designed especially for windows of the sliding sash or double-hung type. The principal object of the invention is to provide a construction of this character which prevents rattling of the sashes and heat exchange through the window when closed.

This object is accomplished by forming the window sashes with inclined slots containing inclined or wedge members yieldably mounted. Spring means acting on these members tend to extend them beyond the upper edge of the upper sash and the lower end of the lower sash. When the sashes are moved into closed position, these members abut the lintel and sill respectively and exert a wedge action of the sashes which brings the latter into firm engagement with the parting strips.

The invention is fully disclosed by way of example in the following description and in the accompanying drawings in which- Figure l is a vertical section of a window construction according to the invention;

Fig. 2 is a fragmentary front elevation thereof; I

Fig. 8 is a fragmentary perspective view of one of the sashes;

Fig. i is a section on the line 4 -4 of Figure 2;

Fig. 5 is a detailed section on the line 5-5 of Fig. 1; and

Fig. 6 is a detailed section of the line 6-6 of Fig. 3. V

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figs. 1 and 2 is illustrated a window frame 1 of usual construction including a sill 2, a lintel 3, parting strips 4 and guide strips 5. In this frame are mounted in the usual manner a lower sash 6 and an upper sash 7.

Each sash has its vertical edges rabbeted to form notches 8 which converge towards the longitudinal center of the frame. Each such notch contains an inclined or wedge member 9 of equal length and having its inclined face in engagement with the inclined face of the corresponding notch. In the surface of the wedge adjacent the edge of the sash is formed a recess '10 which receives the head of a stud or screw 11 anchored in the sash. On the head is mounted a block 12 engaged-by one end of a spring 13 received in the recess, the

other end of the spring bearing against the opposite wall of the recess. This arrangement constitutes a yieldable connection between the sashes and the wedges wherebythe latter are normally projected above the upper edge the pp sash and the lower end of 0 the lower sash as illustrated in Figure 3. The wedges 9 are guided along the side edges of the sashes by headedscrews 14 passed "through comparatively :narrow slots 15 in the wedges and anchored in thezsashes. The heads 16 of the screws are accommodated in countersunk recesses 17 formed in the wedges as illustrated more clearly in Figure 5. When the sashes are moved to closed po sition, the protruding ends thereof abutthe sill 2 or lintel 3, as the case may be. Being bound at their inclined faces by the sashes'and at their straight faces by the strips 5, the wedge members exert a wedge action on the sashes and force them firmly into engagement with the parting strips 4. By the same action the bevelled upper side 18 of the lower sash and the bevelled lower side 19 of the upper sash are clamped firmly together as shown in Figure. 1. Consequently, the sashes are held against rattling and are closed all around to prevent drafts through the window. 7

Although a specific embodiment of the invention has been illustrated and described, 8 it will be apparent that various alterations in i the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

What I claim is V 1. A window comprising a frame, a sash mounted to slide longitudinally therein and having a notch with an inclined wall, a wedge member resiliently mounted in said notch to move longitudinally of said 95 frame and having one end adapted to move longitudinally into engagement with one of the boundaries of said frame.

" 2. A window comprising a frame, a sash slidably mounted therein and having a notch m0 with an inclined wall and carried by said sash, a Wedge member mounted in said notch, and a yieldable connection between said sash and said member acting in the direction of movement of said sash.

3. A window comprising a frame, a sash slidably mounted therein and having a notch with an inclined wall, a wedge member mounted in said notch and having a longitudinal slot, a stud anchored in said sash and extending into said slot, and a spring seated in said member and bearing on said stud to move said member in its lengthwise direction.

4. A window comprising a frame, a sash mounted to slide longitudinally therein and having a notch with an inclined Wall, a wedge member mounted in said notch, a yieldable connection between said sash and said member tending to move said member longitudinally of said frame, and guiding means for said member.

5. A Window comprising a frame, a pair of sashes slidably mounted therein, each sash having a notch with an inclined wall, and wedge members yieldably mounted in said notches, the wedge members in the upper sash being adapted to engage the lintel of the frame, and the wedge members of the lower sash being adapted to engage the sill of the frame.

In testimony whereof I aflix my signature.

CLARENCE G. JOHNSON.
